1. The enhancement effect: with reference concrete slump and under the
premise of dosage of cement, such as water reducing rate can be up to 16 ~ 18%,
concrete age strength were significantly improved, 3 ~ 7 days increase 70 ~ 80%,
28 days can still improve 15-30%.

2. The pumping performance: has significant pumpability. Compared with the
reference concrete, on the premise of the same water-cement ratio, slump the
added value of 100 mm, or 2 hours slump loss rate < 20%.

3. Impermeability index: reduce water consumption, increase the
self-compacting concrete, compared with the reference concrete, the permeability
performance can be improved by more than 50%.

5. The surface is bright and clean, the mixing of concrete with this
product, its viscosity, air content, and secrete water phenomenon is effectively
improved, and make all kinds of concrete surface is bright and clean and
beautiful.

6. Tensile, bending, this product has the function of retarded before early
strength in ensure the premise of content, can meet the needed for 3 d tensioned
concrete strength (with the exception of retarded time) and improve the flexural
strength of 28 d requirements.

Method of use:

This product dosage range of 1.7 ~ 2.2% (in gelled material flow meter),
according to the change of and the adaptability of cement, temperature and
concrete slump requirements, etc., within the scope of the recommended
adjustment to determine the best dosage. Can be directly to powder mixed with,
also can use the mixture solution. On-site mixing, extend 30 seconds, commodity
concrete without extended mixing time. When using this product, should according
to the concrete mixture ratio test and the adaptability of cement in advance.

Scope of application:

This product is suitable for all kinds of pumping concrete, mass concrete,
high-rise buildings, roads, Bridges and hydraulic engineering, underground
engineering and other kinds of pumping construction of concrete, also suitable
for underground and underwater pouring concrete.

Key points:

1. The change of varieties or new cement, cement cement compatibility test
should be done.

2. Must be correct measurement test mixture ratio, and concrete should be
in strict accordance with the construction specification operation.

3. For the retarded concrete, should according to the concrete test with
test setting time in advance.

5. The winter construction of concrete, besides the effect of admixture, at
the same time must be covered with straw bag, plastic film freeze protection
measures, such as strengthen maintenance according to the construction standard.
